Purpose
The purpose of this document is to provide a procedure to help experienced technicians/engineers install and
commission an in-building wireless enhancement repeater system using Westell Technologies digital repeaters. This
document was written to address the practical concerns of the installer. Following the procedures in this manual will
minimize risks associated with modifying a live system and will prevent service interruptions. This document assumes
the technician/engineer understands the basic principles and functionality involved with repeater and in-building
systems.
Application
Apply this guide when adding digital repeater capability to an existing system or as part of a new installation.
Document Organization
This manual includes the following chapters:
Chapter 1: Product Overview –Provides an overview of the DSP85 Repeater Series
Chapter 2: Optimizing the System during Installation –Provides information for optimization of the system
Chapter 3: Web-Based GUI –Provides information about using the system through a web-based graphical user
interface
Chapter 4: Console Interface –Provides information about local access to the repeater through console interface
Appendix A: Attenuation and Dynamic Range Guidelines –Provides information about attenuation and dynamic
range guidelines
Appendix B: Band Plans and Filter File Naming Conventions –Provides information about the band plans and filter
file naming conventions
